Abstract
A three-dimensional electromagnetic (TEM) lens is made of many printed circuit cards for future satellite multiple beam antenna applications. To obtain a low scan aberration lens combined with cross-polarization suppression, the lens array faces have a nonuniform distribution of element rotational orientations, making the array faces electrically nonuniform as to mutual coupling. An experimental procedure is presented for developing dual-band active impedance matched lens elements. Using such elements, a lens is built and tested to verify the adequacy of the design procedure.
